Key legal question
Whether the settlement permit could be revoked for obtaining it by concealment of material facts
Extracted holding
Yes. Concealing the existence of extramarital children amounted to withholding a material fact under the aliens law and justified revocation.
Extracted reasoning
The applicant had a duty of truthful disclosure about all facts relevant to the permit decision. The existence of extramarital children was material because it could affect family reunification and the assessment of the residence situation. He informed the authorities only long after the relevant applications, which supported intentional concealment.
